DWD层（用户行为日志）

6.1.1 日志解析思路

1）日志结构回顾

（1）页面埋点日志

6.1.2 get_json_object函数使用

1）数据

[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]

2）取出第一个json对象

hive (gmall)>
select get_json_object('[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]','$[0]');

结果是：{“name”:“大郎”,“sex”:“男”,“age”:“25”}
3）取出第一个json的age字段的值

hive (gmall)>
SELECT get_json_object('[{"name":"大郎","sex":"男","age":"25"},{"name":"西门庆","sex":"男","age":"47"}]',"$[0].age");

6.1.3 启动日志表

启动日志解析思路：启动日志表中每行数据对应一个启动记录，一个启动记录应该包含日志中的公共信息和启动信息。先将所有包含start字段的日志过滤出来，然后使用get_json_object函数解析每个字段。
在这里插入图片描述

1）建表语句
DROP TABLE IF EXISTS dwd_start_log;
CREATE EXTERNAL TABLE dwd_start_log(`area_code` STRING COMMENT '地区编码',`brand` STRING COMMENT '手机品牌',`channel` STRING COMMENT '渠道',`is_new` STRING COMMENT '是否首次启动',`model` STRING COMMENT '手机型号',`mid_id` STRING COMMENT '设备id',`os` STRING COMMENT '操作系统',`user_id` STRING COMMENT '会员id',`version_code` STRING COMMENT 'app版本号',`entry` STRING COMMENT 'icon手机图标 notice 通知 install 安装后启动',`loading_time` BIGINT COMMENT '启动加载时间',`open_ad_id` STRING COMMENT '广告页ID ',`open_ad_ms` BIGINT COMMENT '广告总共播放时间',`open_ad_skip_ms` BIGINT COMMENT '用户跳过广告时点',`ts` BIGINT COMMENT '时间'
) COMMENT '启动日志表'
PARTITIONED BY (`dt` STRING) -- 按照时间创建分区
STORED AS PARQUET -- 采用parquet列式存储
LOCATION '/warehouse/gmall/dwd/dwd_start_log' -- 指定在HDFS上存储位置
TBLPROPERTIES('parquet.compression'='lzo') -- 采用LZO压缩
;
2）数据导入

判断启动日志的依据，json串中有start字段

hive (gmall)> 
insert overwrite table dwd_start_log partition(dt='2020-06-14')
selectget_json_object(line,'$.common.ar'),get_json_object(line,'$.common.ba'),get_json_object(line,'$.common.ch'),get_json_object(line,'$.common.is_new'),get_json_object(line,'$.common.md'),get_json_object(line,'$.common.mid'),get_json_object(line,'$.common.os'),get_json_object(line,'$.common.uid'),get_json_object(line,'$.common.vc'),get_json_object(line,'$.start.entry'),get_json_object(line,'$.start.loading_time'),get_json_object(line,'$.start.open_ad_id'),get_json_object(line,'$.start.open_ad_ms'),get_json_object(line,'$.start.open_ad_skip_ms'),get_json_object(line,'$.ts')
from ods_log
where dt='2020-06-14'
and get_json_object(line,'$.start') is not null;
3）查看数据

hive (gmall)>
select * from dwd_start_log where dt=‘2020-06-14’ limit 2;

6.1.4 页面日志表

页面日志解析思路：页面日志表中每行数据对应一个页面访问记录，一个页面访问记录应该包含日志中的公共信息和页面信息。先将所有包含page字段的日志过滤出来，然后使用get_json_object函数解析每个字段。
在这里插入图片描述

1）建表语句
DROP TABLE IF EXISTS dwd_page_log;
CREATE EXTERNAL TABLE dwd_page_log(`area_code` STRING COMMENT '地区编码',`brand` STRING COMMENT '手机品牌',`channel` STRING COMMENT '渠道',`is_new` STRING COMMENT '是否首次启动',`model` STRING COMMENT '手机型号',`mid_id` STRING COMMENT '设备id',`os` STRING COMMENT '操作系统',`user_id` STRING COMMENT '会员id',`version_code` STRING COMMENT 'app版本号',`during_time` BIGINT COMMENT '持续时间毫秒',`page_item` STRING COMMENT '目标id ',`page_item_type` STRING COMMENT '目标类型',`last_page_id` STRING COMMENT '上页类型',`page_id` STRING COMMENT '页面ID ',`source_type` STRING COMMENT '来源类型',`ts` bigint
) COMMENT '页面日志表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET

TBLPROPERTIES('parquet.compression'='lzo');
2）数据导入
hive (gmall)>
insert overwrite table dwd_page_log partition(dt='2020-06-14')
selectget_json_object(line,'$.common.ar'),get_json_object(line,'$.common.ba'),get_json_object(line,'$.common.ch'),get_json_object(line,'$.common.is_new'),get_json_object(line,'$.common.md'),get_json_object(line,'$.common.mid'),get_json_object(line,'$.common.os'),get_json_object(line,'$.common.uid'),get_json_object(line,'$.common.vc'),get_json_object(line,'$.page.during_time'),get_json_object(line,'$.page.item'),get_json_object(line,'$.page.item_type'),get_json_object(line,'$.page.last_page_id'),get_json_object(line,'$.page.page_id'),get_json_object(line,'$.page.source_type'),get_json_object(line,'$.ts')
from ods_log
where dt='2020-06-14'
and get_json_object(line,'$.page') is not null;
3）查看数据
hive (gmall)> 
select * from dwd_page_log where dt='2020-06-14' limit 2;

6.1.5 动作日志表

动作日志解析思路：动作日志表中每行数据对应用户的一个动作记录，一个动作记录应当包含公共信息、页面信息以及动作信息。先将包含action字段的日志过滤出来，然后通过UDTF函数，将action数组“炸开”（类似于explode函数的效果），然后使用get_json_object函数解析每个字段。

1）建表语句
DROP TABLE IF EXISTS dwd_action_log;
CREATE EXTERNAL TABLE dwd_action_log(`area_code` STRING COMMENT '地区编码',`brand` STRING COMMENT '手机品牌',`channel` STRING COMMENT '渠道',`is_new` STRING COMMENT '是否首次启动',`model` STRING COMMENT '手机型号',`mid_id` STRING COMMENT '设备id',`os` STRING COMMENT '操作系统',`user_id` STRING COMMENT '会员id',`version_code` STRING COMMENT 'app版本号',`during_time` BIGINT COMMENT '持续时间毫秒',`page_item` STRING COMMENT '目标id ',`page_item_type` STRING COMMENT '目标类型',`last_page_id` STRING COMMENT '上页类型',`page_id` STRING COMMENT '页面id ',`source_type` STRING COMMENT '来源类型',`action_id` STRING COMMENT '动作id',`item` STRING COMMENT '目标id ',`item_type` STRING COMMENT '目标类型',`ts` BIGINT COMMENT '时间'
) COMMENT '动作日志表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET
LOCATION '/warehouse/gmall/dwd/dwd_action_log'
TBLPROPERTIES('parquet.compression'='lzo');
2）创建UDTF函数——设计思路

在这里插入图片描述

3）创建UDTF函数——编写代码

（1）创建一个maven工程：hivefunction
（2）创建包名：com.atguigu.hive.udtf
（3）引入如下依赖

org.apache.hivehive-exec3.1.2

（4）编码

package com.atguigu.hive.udtf;import org.apache.hadoop.hive.ql.exec.UDFArgumentException;
import org.apache.hadoop.hive.ql.metadata.HiveException;
import org.apache.hadoop.hive.ql.udf.generic.GenericUDTF;
import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspector;
import org.apache.hadoop.hive.serde2.objectinspector.ObjectInspectorFactory;
import org.apache.hadoop.hive.serde2.objectinspector.PrimitiveObjectInspector;
import org.apache.hadoop.hive.serde2.objectinspector.StructObjectInspector;
import org.apache.hadoop.hive.serde2.objectinspector.primitive.PrimitiveObjectInspectorFactory;
import org.json.JSONArray;import java.util.ArrayList;
import java.util.List;public class ExplodeJSONArray extends GenericUDTF {@Overridepublic StructObjectInspector initialize(ObjectInspector[] argOIs) throws UDFArgumentException {// 1 参数合法性检查if (argOIs.length != 1) {throw new UDFArgumentException("explode_json_array 只需要一个参数");}// 2 第一个参数必须为string//判断参数是否为基础数据类型if (argOIs[0].getCategory() != ObjectInspector.Category.PRIMITIVE) {throw new UDFArgumentException("explode_json_array 只接受基础类型参数");}//将参数对象检查器强转为基础类型对象检查器PrimitiveObjectInspector argumentOI = (PrimitiveObjectInspector) argOIs[0];//判断参数是否为String类型if (argumentOI.getPrimitiveCategory() != PrimitiveObjectInspector.PrimitiveCategory.STRING) {throw new UDFArgumentException("explode_json_array 只接受string类型的参数");}// 3 定义返回值名称和类型List fieldNames = new ArrayList();List fieldOIs = new ArrayList();fieldNames.add("items");fieldOIs.add(PrimitiveObjectInspectorFactory.javaStringObjectInspector);return ObjectInspectorFactory.getStandardStructObjectInspector(fieldNames, fieldOIs);}public void process(Object[] objects) throws HiveException {// 1 获取传入的数据String jsonArray = objects[0].toString();// 2 将string转换为json数组JSONArray actions = new JSONArray(jsonArray);// 3 循环一次，取出数组中的一个json，并写出for (int i = 0; i < actions.length(); i++) {String[] result = new String[1];result[0] = actions.getString(i);forward(result);}}public void close() throws HiveException {}}
4）创建函数

（1）打包

（2）将hivefunction-1.0-SNAPSHOT.jar上传到hadoop102的/opt/module，然后再将该jar包上传到HDFS的/user/hive/jars路径下

[atguigu@hadoop102 module]$ hadoop fs -mkdir -p /user/hive/jars
[atguigu@hadoop102 module]$ hadoop fs -put hivefunction-1.0-SNAPSHOT.jar /user/hive/jars

（3）创建永久函数与开发好的java class关联

create function explode_json_array as 'com.atguigu.hive.udtf.ExplodeJSONArray' using jar 'hdfs://hadoop102:8020/user/hive/jars/hivefunction-1.0-SNAPSHOT.jar';

（4）注意：如果修改了自定义函数重新生成jar包怎么处理？只需要替换HDFS路径上的旧jar包，然后重启Hive客户端即可。

5）数据导入

insert overwrite table dwd_action_log partition(dt='2020-06-14')
selectget_json_object(line,'$.common.ar'),get_json_object(line,'$.common.ba'),get_json_object(line,'$.common.ch'),get_json_object(line,'$.common.is_new'),get_json_object(line,'$.common.md'),get_json_object(line,'$.common.mid'),get_json_object(line,'$.common.os'),get_json_object(line,'$.common.uid'),get_json_object(line,'$.common.vc'),get_json_object(line,'$.page.during_time'),get_json_object(line,'$.page.item'),get_json_object(line,'$.page.item_type'),get_json_object(line,'$.page.last_page_id'),get_json_object(line,'$.page.page_id'),get_json_object(line,'$.page.source_type'),get_json_object(action,'$.action_id'),get_json_object(action,'$.item'),get_json_object(action,'$.item_type'),get_json_object(action,'$.ts')
from ods_log lateral view explode_json_array(get_json_object(line,'$.actions')) tmp as action
where dt='2020-06-14'
and get_json_object(line,'$.actions') is not null;
3）查看数据
select * from dwd_action_log where dt='2020-06-14' limit 2;

6.1.6 曝光日志表

曝光日志解析思路：曝光日志表中每行数据对应一个曝光记录，一个曝光记录应当包含公共信息、页面信息以及曝光信息。先将包含display字段的日志过滤出来，然后通过UDTF函数，将display数组“炸开”（类似于explode函数的效果），然后使用get_json_object函数解析每个字段。

在这里插入图片描述

1）建表语句
DROP TABLE IF EXISTS dwd_display_log;
CREATE EXTERNAL TABLE dwd_display_log(`area_code` STRING COMMENT '地区编码',`brand` STRING COMMENT '手机品牌',`channel` STRING COMMENT '渠道',`is_new` STRING COMMENT '是否首次启动',`model` STRING COMMENT '手机型号',`mid_id` STRING COMMENT '设备id',`os` STRING COMMENT '操作系统',`user_id` STRING COMMENT '会员id',`version_code` STRING COMMENT 'app版本号',`during_time` BIGINT COMMENT 'app版本号',`page_item` STRING COMMENT '目标id ',`page_item_type` STRING COMMENT '目标类型',`last_page_id` STRING COMMENT '上页类型',`page_id` STRING COMMENT '页面ID ',`source_type` STRING COMMENT '来源类型',`ts` BIGINT COMMENT 'app版本号',`display_type` STRING COMMENT '曝光类型',`item` STRING COMMENT '曝光对象id ',`item_type` STRING COMMENT 'app版本号',`order` BIGINT COMMENT '曝光顺序',`pos_id` BIGINT COMMENT '曝光位置'
) COMMENT '曝光日志表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET

2）数据导入
insert overwrite table dwd_display_log partition(dt='2020-06-14')
selectget_json_object(line,'$.common.ar'),get_json_object(line,'$.common.ba'),get_json_object(line,'$.common.ch'),get_json_object(line,'$.common.is_new'),get_json_object(line,'$.common.md'),get_json_object(line,'$.common.mid'),get_json_object(line,'$.common.os'),get_json_object(line,'$.common.uid'),get_json_object(line,'$.common.vc'),get_json_object(line,'$.page.during_time'),get_json_object(line,'$.page.item'),get_json_object(line,'$.page.item_type'),get_json_object(line,'$.page.last_page_id'),get_json_object(line,'$.page.page_id'),get_json_object(line,'$.page.source_type'),get_json_object(line,'$.ts'),get_json_object(display,'$.display_type'),get_json_object(display,'$.item'),get_json_object(display,'$.item_type'),get_json_object(display,'$.order'),get_json_object(display,'$.pos_id')
from ods_log lateral view explode_json_array(get_json_object(line,'$.displays')) tmp as display
where dt='2020-06-14'
and get_json_object(line,'$.displays') is not null;
3）查看数据
select * from dwd_display_log where dt='2020-06-14' limit 2;

6.1.7 错误日志表

错误日志解析思路：错误日志表中每行数据对应一个错误记录，为方便定位错误，一个错误记录应当包含与之对应的公共信息、页面信息、曝光信息、动作信息、启动信息以及错误信息。先将包含err字段的日志过滤出来，然后使用get_json_object函数解析所有字段。

在这里插入图片描述

1）建表语句
DROP TABLE IF EXISTS dwd_error_log;
CREATE EXTERNAL TABLE dwd_error_log(`area_code` STRING COMMENT '地区编码',`brand` STRING COMMENT '手机品牌',`channel` STRING COMMENT '渠道',`is_new` STRING COMMENT '是否首次启动',`model` STRING COMMENT '手机型号',`mid_id` STRING COMMENT '设备id',`os` STRING COMMENT '操作系统',`user_id` STRING COMMENT '会员id',`version_code` STRING COMMENT 'app版本号',`page_item` STRING COMMENT '目标id ',`page_item_type` STRING COMMENT '目标类型',`last_page_id` STRING COMMENT '上页类型',`page_id` STRING COMMENT '页面ID ',`source_type` STRING COMMENT '来源类型',`entry` STRING COMMENT ' icon手机图标  notice 通知 install 安装后启动',`loading_time` STRING COMMENT '启动加载时间',`open_ad_id` STRING COMMENT '广告页ID ',`open_ad_ms` STRING COMMENT '广告总共播放时间',`open_ad_skip_ms` STRING COMMENT '用户跳过广告时点',`actions` STRING COMMENT '动作',`displays` STRING COMMENT '曝光',`ts` STRING COMMENT '时间',`error_code` STRING COMMENT '错误码',`msg` STRING COMMENT '错误信息'
) COMMENT '错误日志表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET
LOCATION '/warehouse/gmall/dwd/dwd_error_log'
TBLPROPERTIES('parquet.compression'='lzo');

说明：此处为对动作数组和曝光数组做处理，如需分析错误与单个动作或曝光的关联，可先使用explode_json_array函数将数组“炸开”，再使用get_json_object函数获取具体字段。

4）数据导入
insert overwrite table dwd_error_log partition(dt='2020-06-14')
selectget_json_object(line,'$.common.ar'),get_json_object(line,'$.common.ba'),get_json_object(line,'$.common.ch'),get_json_object(line,'$.common.is_new'),get_json_object(line,'$.common.md'),get_json_object(line,'$.common.mid'),get_json_object(line,'$.common.os'),get_json_object(line,'$.common.uid'),get_json_object(line,'$.common.vc'),get_json_object(line,'$.page.item'),get_json_object(line,'$.page.item_type'),get_json_object(line,'$.page.last_page_id'),get_json_object(line,'$.page.page_id'),get_json_object(line,'$.page.source_type'),get_json_object(line,'$.start.entry'),get_json_object(line,'$.start.loading_time'),get_json_object(line,'$.start.open_ad_id'),get_json_object(line,'$.start.open_ad_ms'),get_json_object(line,'$.start.open_ad_skip_ms'),get_json_object(line,'$.actions'),get_json_object(line,'$.displays'),get_json_object(line,'$.ts'),get_json_object(line,'$.err.error_code'),get_json_object(line,'$.err.msg')
from ods_log
where dt='2020-06-14'
and get_json_object(line,'$.err') is not null;
5）查看数据
hive (gmall)> 
select * from dwd_error_log where dt='2020-06-14' limit 2;

6.1.8 DWD层用户行为数据加载脚本

1）编写脚本

（1）在hadoop102的/home/atguigu/bin目录下创建脚本

[atguigu@hadoop102 bin]$ vim ods_to_dwd_log.sh

在脚本中编写如下内容

（2）增加脚本执行权限

[atguigu@hadoop102 bin]$ chmod 777 ods_to_dwd_log.sh
2）脚本使用

（1）执行脚本

[atguigu@hadoop102 module]$ ods_to_dwd_log.sh all 2020-06-14

（2）查询导入结果

DWD层（业务数据）

业务数据方面DWD层的搭建主要注意点在于维度建模。

6.2.1 评价事实表（事务型事实表）

1）建表语句

CREATE EXTERNAL TABLE dwd_comment_info(`id` STRING COMMENT '编号',`user_id` STRING COMMENT '用户ID',`sku_id` STRING COMMENT '商品sku',`spu_id` STRING COMMENT '商品spu',`order_id` STRING COMMENT '订单ID',`appraise` STRING COMMENT '评价(好评、中评、差评、默认评价)',`create_time` STRING COMMENT '评价时间'
) COMMENT '评价事实表'
PARTITIONED BY (`dt` STRING)
STORED AS PARQUET
